Phylogenetic tree was built by the neighbour-joining method based on 16S rRNA sequences of the 75 isolated strains. Strain names in blue corresponded to isolates from Tetragonisca fiebrigi samples; on the other hand, the strain names in red were from Scaptotrigona jujuyensis. Bacillota strains are highlighted in green, whereas isolates from the Pseudomonadota phylum are highlighted in orange, and strains from the Actinomycetota phylum are highlighted in yellow. Bar 5 substitutions per nucleotide position. All ambiguous positions were removed for each sequence pair (pairwise deletion option). There was a total of 3086 positions in the final dataset.
